It's GOOD

When New York City started adding more bike lanes to city streets, drivers complained that it would slow down traffic. But studies from the transportation department show that the opposite has actually happened: traffic got just a little bit faster in the most crowded areas, even though there's still the same number of cars. I'm curious why that's happening—anyone have any theories?
